If genes were lights on a string of DNA, the genome would appear as an endless flicker, as thousands of genes come on and off at any given time. Tim Hughes, a Professor at the University of Toronto's Donnelly Centre, is set on figuring out the rules behind this tightly orchestrated light-show, because when it fails, disease can occur.

Genes are switched on or off by proteins called transcription factors. These proteins bind to precise sites on the DNA that serve as guideposts, telling transcription factors that their target genes are nearby.

In their latest paper, published in Nature Biotechnology, Hughes and his team did the first systematic study of the largest group of human transcription factors, called C2H2-ZF.

The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger than that of our closest living relative, the chimpanzee, if almost all of our genes are the same?

Mandarin-speaking Chinese more likely to read emotions in the voices of others, while English-speaking North Americans rely more on facial expressions, according to a new paper. That may be why Americans think Chinese language is exaggerated while the Chinese believe Americans are too physically expressive.

Yet it isn't just a style issue, it can be seen in brain activity.

Stockholm is considered the world's most sunlight-deprived capital - in November of 2014 the Swedes living there had just a few hours of the stuff and in winter months, it will get dark at 3 PM anyway, so if the sun is hidden by clouds, it can be a real downer. 

Yet not everywhere in Sweden is so bleak. Because there are so few solar laboratories in the world, KTH Royal Institute of Technology reasoned that Stockholm was the perfect place to build one and in there, the future is bright 24 hours a day.

Regular concert-goers are used to seeing singers use expressive and even very dramatic facial expressions - that's because it works.

Music and speech are alike in that they use both facial and acoustic cues to engage listeners in an emotional experience and so  a team of researchers at McGill University wondered what roles these different cues played in conveying emotions.

If wind and solar companies want to continue to get government money, they should take a page out of the natural gas playbook - a new economic analysis found that just three state grants to support natural gas programs totaling $52.9 million generated $128 million in economic impact and 927 full-time jobs in 2014. 

The Texas Commission on Environmental Quality (TCEQ) administered the three grants: the Clean Transportation Triangle (CTT), the Alternative Fueling Facilities Program (AFFP) and the Texas Natural Gas Vehicle Program (TNGVP).
